well, my betta hasn't been eating to my knowledge, I've never seen him come to the surface for food, but i have seen him sort of rummaging through thew bottom of the tank for scraps.
he isn't starving because i have to feed more than enough to make sure my bottom feeder gets food, so they have been sharing these tropical flakes. and whenever i put in the betta food, the platys eat it, or push it into a corner.
i feed them right before i leave too, and when i come back all the food in the tank is gone. i also realized that the betta food says color enhancing, and since i got him his colors are way more vivid. so could it be that his eating habits are slightly off schedule than the rest of the fish, or is he becoming a bottom feeder?
